Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color temperature adjustment methods for terminals are limited, making it difficult to achieve a target color temperature that matches ambient conditions, requiring professional knowledge and restricting the adjustment range, which affects user experience and visual comfort.
Innovation Solution
A color temperature adjustment method that integrates user input and ambient light data to provide an intuitive, broad adjustable range, converting input operations into color parameters and compensating for color temperature differences to match human visual adaptation characteristics, using a graphical user interface with a color temperature adjustment region and ambient light sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single progress bar or three progress bars are used for color temperature adjustment, then the adjustment interface is simple, but the adjustment range is limited and it is difficult to obtain a target color temperature that matches ambient conditions
Solution Approach 1:
The patent transitions from one-dimensional progress bar adjustment to two-dimensional color temperature adjustment region. The adjustment region includes multiple operation points with different color temperatures, allowing users to select from a broader range of color temperatures by touching different positions on the screen. This dimensional expansion resolves the contradiction by providing extensive adjustment range while maintaining interface simplicity through intuitive touch interaction.
2Measurement precision
If RGB parameters are adjusted directly, then the color temperature can be precisely controlled, but professional knowledge is required and the operation becomes difficult
Solution Approach 1:
The patent introduces an intermediary adjustment region between the user and the RGB parameters. Instead of directly adjusting RGB values, users interact with the adjustment region that contains multiple operation points, each corresponding to predetermined RGB parameters. This intermediary layer simplifies operation by eliminating the need for professional color knowledge while maintaining precise color temperature control through the predetermined parameter sets.
3Adaptability or versatility
If the adjustment range on progress bars is limited, then the interface remains simple, but the terminal cannot obtain target color temperature that matches ambient condition
Solution Approach 1:
The patent applies preliminary action by pre-setting multiple operation points in the adjustment region, each corresponding to predetermined RGB parameters for different color temperatures. This allows the system to quickly adapt to ambient conditions by selecting from pre-configured options rather than requiring complex real-time calculations. The ambient light sensor detects ambient light levels and automatically selects the most appropriate operation point, achieving ambient adaptation without complex adjustment mechanisms.

AI summary
A method includes detecting an input operation performed on a display screen of a terminal when the display screen is touched and when a color temperature adjustment region is displayed on the display screen, converting, in response to the input operation, coordinates of an operation point corresponding to the input operation into a first color parameter, obtaining ambient light converting a color parameter of the ambient light into a second color parameter, integrating the first color parameter and the second color parameter to obtain a third color parameter, converting the third color parameter into a target color parameter, and displaying the target color parameter on the display screen of the terminal.
